Adobe Systems released security patches Tuesday for ColdFusion, Flex and Flash Player, the latter addressing a flaw for which is an exploit is already available.

The Flash Player updates, namely Flash Player 17.0.0.169 for Windows and Mac, Flash Player 11.2.202.457 for Linux and Flash Player Extended Support Release 13.0.0.281, address a total of 22 vulnerabilities, most of which are critical and can lead to remote code execution.

One of the flaws, tracked as CVE-2015-3043 in the Common Vulnerabilities and Exposures (CVE) database, has been known by attackers since before Adobe released its latest patches. This makes it a so-called zero-day vulnerability -- a flaw for which a fix was not yet available when it began being exploited.

"Adobe is aware of a report that an exploit for CVE-2015-3043 exists in the wild, and recommends users update their product installations to the latest versions," the company said in a security advisory.

Adobe also released hotfixes for versions 11 and 10 of its ColdFusion Web application development platform. The patches address an input validation issue that can be exploited to launch reflected cross-site scripting (XSS) attacks.

A similar vulnerability was found and patched in Adobe Flex 4.6, more specifically in its ASdoc Tool component. Users are advised to download a fixed version of the index.html file and replace the one currently deployed on their websites.
